The glass ceiling of the 19th-century Ashkenazi synagogue. This historical treasure is hidden away at the back of an 18th-century Huguenot silk weaver’s house at No19 Princelet Street. In a building that seems to harbour secrets, one of its most seductive concerns the mysterious attic inhabitant David Rodinsky, a man so reclusive that even neighbours of 30 years barely knew of his existence, much less his disappearance in the 1960s. The story is eked out in Rachel Lichtenstein’s book Rodinsky’s Room, written in collaboration with Iain Sinclair.
